Astrometric differences of run 3629 relative to a number of alternative catalogs, where available.

The left column shows full residuals for each camcol. Red dots indicated camcols that are out of spec relative to the comparison catalog (> 20.00 mas off in the median).

The following columns show offsets per field for each camcol, in RA and in Dec.

• Catastrophically bad fields are shown in red (> 500 mas off, or > 10.0 mas/yr for proper motions).
• Runs of bad fields are shown in pink (> 100 mas off, or > 2.5 mas/yr for proper motions).
• Individual bad fields are shown in yellow (> 200 mas off, or > 5.0 mas/yr for proper motions).

Fields that are individually bad, and are part of a bad run of fields appear orange.
